Application lcd April 23, 1919. Serial No. 292,075.

To all whom it may conce-m:

Be it known that I, LOUIS C. IsAAcsoN, a citizen of the United States, residin at Denver, in the county of Denver and tate of Colorado have invented certain new and useful improvements in Bottle-Stopp ers, of which the following is a specification.

My invention relates to bottle Stoppers and more particularly to improvements in the paper disk-shaped, Stoppers commonly luse-d to close the mouths of milk bottles, by air-tight engagement with a seat inthe upper portion of the neck thereof.

It is the primary object of my invention to provide a` stopper having all the essential characteristics of those at present in common use, with a movable lid to produce an opening through which the contents of a bottle may be discharged without the stopper being removed from lthe seat in the neck thereof.

Another object ofthe invention resides in providing a stopper of this nature in which the movable lid is hermetically sealed by readily severed means until its adjustment is desired for the purpose of obtaining part or all of the contents of the bottle.

The use of my invention obviates the removal of the stopper to pour the liquid from a bottle to l'whichit is applied and thereby prevents contamination of the fluid by foreign substances adhering to the stopper upon its being replaced after removal, eliminates the necessity of puncturing the stopper for its removal as is required in most Stoppers at present in use, simplifies the work of opening the bottle for the discharge of its contents and does away with the danger of s lashingand spilling incident to the sud'- cen separation of the stopper from the mouth of the bottle, and with the annoyance and difficulty of replacing it after it is bent or broken, and its seat in the neck of the bottle is covered with the liquid.

An embodiment of my invention has been shown in the accompanying drawings in the various'views of which like parts are designated by similar reference characters, and 1n which-J Figure 1 is a plan view of the stopper without its sealing member;

Fig. 2, a similar view of the stopper after the sealing member is applied thereto; yFig. 3, a section through the upper portion of the neck of a milk-bottle showing my improved stopper in its closed position thereon;

F 1g. 4, a similar section showing the stopper with its adjustable lid in the open position, and

Fig. 5., a section taken on the line 5 5,

tion of the stopper.

The stopper consists of a disk 4 made as usual of wood, fiber, orvother inexpensive substance, which fits snugly inside the neck of the bottle and upon the seat thereof. 'lwo slits 5 which extend convergently from the periphery of the disk, -form a lid 6 which may be lifted by bending it along the uncut line 7 between the ends of the slits, to provide an opening for the discharge of the contents of the bottle when the stopper is in place thereon.

strip 8 'of cloth or other flexible material is placed over the lid'and the slitsby which it is defined and upon the immediately adjoining portions of the body of the disk and is secured thereto by means of a suitable adhesive. A portion of the strip projects beyond the peripheral edge of the lid to provide a'tab 9 by means of which it may be lifted, and a clenched staple l0 passes through the cloth strip to aid in securing it to the lid. lf necessary a similar staple 101 may beused to secure the strip rearward of the hinge.

The stopper is applied to the bottle in the usual manner .with its tab projecting upwardly across the rim thereof as shown in Fig. 2.

The cloth strip pasted across the slits, hermetically seals the same and at the same timereinforces the bending line about which the lid moves when brought to its open position.

When it is desired to discharge all or part of the contents of the bottle, the tab is pulled away from the rim of its neck to move the lid to the open position shown in Fig. 4 of the drawings. The pull exerted' on the tab causes the wing portions of the strip to separate from the surface of the body portion of the stopper, .and lifts thev 11o i i -lid by ,moving a abeti the-benda. 1in@ 7 which as statedbefore, is reinforce by the portion of thestrip pasted across the same.

When the bottle is but 'partially emptied, the lidis replaced in its original position and the wings of the cloth strip projectlng vacross the edges of its opening closev the same against the entrance of dust and dirt.

The slits in the cover are readily produced in the same operation by which the disk is formed and the strip of cloth can be mechanicallyr applied in a very simple manner so that with but little extra expense a stopper can be produced which in addition to the essential features of the ordinary stopper, lhas the-advantage of providing a material lfastened to the 11d and having wing-portions extending across the slits.

2. A bottle-stopper comprising a disk having slits defining a lid integral with its body portion and movable about a determinate bending-line, and a piece of flexible material fastened to the lid and having wing-portions extending the disk, and a tab-portlon extending across 'the peripheral edge of the same.

3. A bottle stopper 4comprisin a disk having slits defining a lid integra with its body portion and movable about a determinate bending-line, and a piece of flexible .material lfastened to the lid and across the tending across said slits.
